The PRTC19.94TR1800WMCX is a positive temperature coefficient (PTC) thermistor manufactured by AVX Corp/Kyocera Corp. It is designed to protect circuits from overcurrent conditions by increasing resistance when the temperature rises due to excessive current flow. This device is a surface mount device (SMD) and offers reliable circuit protection in a compact package.

Applications:

  
• Overcurrent protection in automotive electronics
  
• Protection of sensitive electronic components in industrial equipment
  
• USB port protection
  
• Power supply protection
  
• Motor overload protection

Features:

  
• Positive Temperature Coefficient (PTC) characteristic
  
• Surface Mount Device (SMD) package
  
• Fast trip time
  
• Low resistance in normal operation
  
• High resistance in tripped state
  
• Compact size

Benefits:

  
• Provides reliable overcurrent protection
  
• Resettable protection: automatically returns to normal operation after the fault is cleared
  
• Reduces the risk of fire and damage to electronic components
  
• Enhances the safety and reliability of electronic devices
  
• Easy to integrate into circuit designs due to its SMD package
